WINDOW FASTENER.

Application filed April 22, 1326. Serial No. 103,987,

The object of my present invention, broad- 1y stated, is the provisionof a new and novel arrangement which may be installed in connection withordinary windows whereby the window may be partly closed or fully closedby a person located at a distance therefrom, the construction of theoperating means be ing simple in character, positive in operation, easyof installation and operation, and which can be manufactured and sold ata comparatively low price.

. .One ma-nner ofcarrying out the principles of this invention in apractical, eflicient, and economical manner, is shown in theaccompanying drawings, inwhichFigure l is an elevation of a portion of awindow frame, looking toward theedges of e sashes, which are closed.Figure 2 is an elevation of apertion of a window, taken right-angles toFig. 1 partly in section ta tea on line 2-2 of Fig. 1, showing themechanisms for the two sashes and also indicating the sashes as closed;Figure 3 shows aportion of a window, taken at right-angles to Fig. 1,but showing the sashes as opened. Figure 4 is a face view of one of theenclosing plates, and showing parts of the mechanism through aperturestherein, Figure 5 is a face view of one of the racks. AndFigure 6 is adiagram of the wiring, in connection with certain of the parts.

Similar indices denote like parts throughout the several views.

In order that the construction, the operation, and the severaladvantages of my invention may he more fully understood and appreciatedI will now take up a detailed description thereof, in which I set forththe same as comprehensively as I may.

In the drawings numeral 1 denotes a portion of one side of a windowframe.

Slidably mounted to move up and down in the frame 1 are the usual sashes2 and 3, each surroundin and carrying a transparency, 4

I n at and 5, respectively.

In the upper portion of each side of the frame 1 apertures are formed inwhich are mounted the usual channeled pulleys 6 and 7, over whichoperate the respective sash cords 8 and 9, one end of each being securedto the upper portion of the respective sashes 2 and 3, in the usualmanner, and their other ends are secured to their respective weights 10and 11. It, of course, is to be understood that the other side of theframe (not shown) and sashes are likewise equipped with pulleys, cords,and weights, identical with that shown. Said weights are such as tonormally close said sash to their limits of movement, raising orlowering them automatically when released.

All of said parts are of ordinary construction and I make no claimthereto, neither am I to be limited to the same.

Located at any convenient place, for instance the upper part of theframe 1 as Shown, is a transformer 12, from one end of which extends theusual double wirin 13, which is of any suitable length such as to extendto a socket connected with the usual electric wiring of the building.Said double wire is connected into a screw plug 14 which is adapted tobe inserted in said socket whereby electric current may be provided tooperate my devices.

The remainder of the construction, that is the trigger devices, are induplicate, one for each of the sashes, therefor-eadescription of onewill answer for both, however I will now describe the upper one of saiddevices, and the members of the other will be denoted by like referencecharacters.

Formed through the side of the frame are the oblong apertures A, one inalinement with the edge of each sash, each is covered by a plate 15,which-is let in flush with the inner face of the side of thefra-mc 1, towhich it is secured by screws 16, which are inserted through theapertures 17 of the plate. Formed through the central part of the plate15 is a square aperture 18, the material by which it is formed beingturned back at rightangles to form cars 19. A bolt 20 is disposed acrossthrough said ears to form a pivot for, and at the lower end of, thetrigger 21. Also formedthrough the plate 15, near one end thereof, is anaperture 22.

One end of the trigger 21 is turned inward at right angles forming atooth 23 which extends through the aperture 22, and normally would slidein contact with the edge of the sash. The other end portion of thetrigger 21 is turned outward, opposite of the tooth 23, and atrightangles to the body of the trigger 2 1 and forms an armature 2&, forthe purpose hereinafter set forth,

Secured in the edge of each sash is a rack 28 with which the teeth 23are adapted to, en-

hailing horizontal .faces forming shoulders,

Said racks are formed with notches and angular faces connecting saidhorizontal iaces, substantially as shown in the drawings. Connectedaround the pro ecting end per tions of the bolt 20, with its' endssecured Figs. 2 and 3.

thereby, is a coil spring 29 whose central portion forms a loop whichcontacts with the trigger 21 and retains it resiliency in contact withthe back of the plate 15, with the tooth 23 projecting throughtheaperture 22, as in For the uppersash said device, including the plate 15and the parts connected thereto, and'the rack 28, is arranged as shownin the upper portion of Figs. 1, 2 and 3, while for the lower sash saidparts are reversed, that is they are arranged as shown in the lowerportions of Figs; 1, 2 and 3, that is they are turned end-for-end.

It will now be apparent that if the upper sash be lowered,.:trom itsclosed position in Figs. 1 and 2, that the tooth 23 will be pressedoutward by the angular faces of the rack 28 and, by reason of the spring29, will be caused 1 to engage one of the shoulders ofthe rack, as

in Fig. 3, thereby preventing the sash from being closed'by the-weights.The lower sash will operate in the same manner except that the movementswill be reversed from that stated. i V c In order to release the tooth23 from the shoulders of the rack electric means are provided inconnection with the transformer,

which means I will now describe in detail.

Numeral 30 denotes a push button ior the control of the upper sash, and31. denotes the gush-button for controlling'the lower sash. aid buttonsmaybe on the same plate, or

connected with the same switch, or they'may be spaced some distanceapart as desired.

The transformer has two terminals, 32and 33. Extending from the terminal32 is a wire 34, which is connected directly with one pole of the uppercoil 26. Also extending from terminal 32 is a wire 35 which connects-directly with a like pole-of the lower coil 26.

Extending from the terminal 33 is a wire 36 which connects with one poleofthe switch and extending from the terminal 33 is a wire 37. whichconnects with one pole of the i switch 31.

Extending from the other pole of the switch 30 is a wire 38, whichconnects with the other It, now, the screw plug 14 be connected with theusual lighting system of a building,

the upper coil, magnetizing the upper core 27, which will attract itsarmature 24 thereto,

thereby slightly turning the upper trigger 21 and causing the tooth 23to move out of engagement with its rack 28 and therefore leaving theupper sash free to be raised by its weights. In like manner by closingthe switch 31 the lower sash will be lowered and closed in thesame way.

' The transformer 12 should be of the proper capacity to change theusual current of the light system into current that is suitable formagnetizing the coils 26'to'the .proper deree. b Now when the switch 30is closed it will be seen that a circuit will be established from onepole of the transformer, that is from the terminal 32, through the wire34, the upper coil 26, the wire 38, the switch30, the wire 36, and thento the terminal 33 of the transformer 12, thereby, completing thefirst'circuit.

In like manner when the switch 31 is closed circuit will. be establishedfrom the ter minal 32,through-the wire'35, the lower coil 26, the wire39, the switch 31, andthe wire 37, to the terminal 33 of the transformer12, thereby completing the second circuit. By the above arrangement itis evident that each circuit is complete per se, yet both drawingcurrent from the same source of power.

In practice the weights 10. for the sash 2 should be of greater. weightthan the sash 2,in order that the sash 2 will move upwardautoinatically'to closed position when it is released.- Alsothe weights11 for the lower sash 3'should be of less weight than is the sash 3, inorder that thes'ash 3 will move downward automatically to closedposition when it is released.

By reason of the plurality of shoulders formed by the rack 28 it isevident that the sashes may be opened and suspended at various degreesof elevation, and then they may be closed from any point where they areleft by simply pressing thebutton of the switch30 or 31, thatis to sayby closing one or both of said switches. By quickly closing and openingone of'th-e switches it is evident that the sash may be allowed to movea step at a time, moving thetooth 23from one to another of the shouldersof the rack, thereby enabling one to only partly close the sashes ifdesired. i 7

It is to be understood that various changes may be made in the detailsherein set forth without departing from the spirit. of my invention orsacrificing any of the advantages thereof. 3

Having now fully shown and described my invention, what I claim anddesire to secure by Letters Patent, is-

In combination with a window-frame having an upper and a lower sashslidable up and down therein, a mechanism for each sash secured inapertures in said frame and each comprising a plate secured over anaperture in said frame and a square aperture formed through said plate,ears extending out from thesides of said square aperture, a piv0tboltextending across through said cars, a trigger pivoted at its lower endto said bolt, a tooth forming the inner terminal of the trigger andwhich extends through a second aperture in said plate and normally incontact with the edge of its sash, an armature formed by the outerportion of said trigger, an induction coil carried by said plate withits core located near said armature, a spring attached to said bolt andto the trigger to normally retain the trigger in contact with said platewith said tooth projecting through said second aperture in the plate,and means whereby said induction coil may be magnetized and demagnetizedby a person located at a distance therefrom, all substantially as shownand described and for the purposes set 1!
